Philips B6X12A valve radio

This is my postwar Philips B6X12A valve radio from 1962. The amplifier is designed in such a way you bi-amplify effect.Bi-amplify is just separating your high tones from your low tones and running them through their own separate amplifier.

Reason for the revision

The sound was very dull when I've first played the radio. After a while the sound stopped working as well.So I saw the opportunity for doing a revision.

I've basically did some basic repairs, just replace the old capacitors and carbon resistors with new ones of equal value (or a little bit higher).The new resistors are metal film type ranging from 1, 2 or 3 Watts of power dissipation.

There is also a 4 Watt resistor in use, you need to get creative in replacing this one, because it's taking all the "hits" from the rectifier valve.I've combined 4 x 33 Ohms 10 Watts to give me 132 Ohm and 40 Watts.
